Psychosocial correlates of psychiatric diagnoses and maladaptive behaviour in youth with severe developmental disability

Stressful life events, post-traumatic stress disorder symptoms and mental health in individuals with intellectual disabilities: a scoping review

BACKGROUND

Stressful life events are events that do not fulfil the A criterion of PTSD in the DSM-5(TR) but are perceived as negative by the person. There is an ongoing debate about the usefulness of the A criterion as a gate criterion for PTSD, and especially regarding which events qualify as traumatic or stressful life events. This debate is particularly important for individuals with intellectual disabilities (ID) or borderline intellectual functioning (BIF), as they seem to be more likely to experience traumatic and stressful life events than their peers without ID-BIF and appear to be more susceptible to the disruptive effects of these events. As a result, people with ID-BIF are more likely to develop mental health and behavioural problems. There is insufficient knowledge about how the relationship between stressful life events and PTSD symptoms should be interpreted, how traumatic and stressful life events are defined and distinguished in people with ID, and whether the A criterion should be broadened for individuals with ID-BIF. The aim of this scoping review was to understand stressful life events and their relationship with PTSD symptoms, other mental health and/or behavioural problems in individuals with ID-BIF.

METHODS

The scoping review was conducted in accordance with the JBI methodology for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR).

RESULTS

Thirty-eight studies were included. Five studies focused on stressful life events and PTSD symptoms. The other studies examined associations between stressful life events and other mental health and/or behavioural problems. Most of the studies did not clearly differentiate between stressful and traumatic events according to the A criterion of PTSD in the DSM-IV (TR) or DSM-5(TR). Of the six studies in which stressful life events were specified and could be distinguished from traumatic events, one found a positive association between PTSD symptoms and stressful life events and five showed weak to strong positive associations with other mental health and/or behavioural problems.

CONCLUSIONS

PTSD symptoms following stressful life events in individuals with ID-BIF are underrepresented in the literature. The lack of a clear definition of stressful life events leads to a gap in the knowledge on whether and how stressful life events may lead to PTSD symptoms, other mental health and/or behavioural problems in individuals with ID-BIF. Therefore, no general conclusions or recommendations can be made regarding the appropriateness of the PTSD A criterion for individuals with ID-BIF. Further research is needed to establish the role of stressful life events in relation to PTSD symptoms and to inform the assessment and effective treatment in people with ID-BIF, as expert clinical experience studies suggest that broadening the PTSD A criterion should be considered for people with ID-BIF.

Long-term effectiveness and generality of practical functional assessment and skill-based treatment

There are several considerations to address when conducting functional communication training for challenging behavior in a school setting, such as the need for schedule thinning and maintenance across staff and the need to establish a variety of appropriate classroom skills. There are several strategies for conducting schedule thinning following functional communication training and for transferring effects across people or settings. However, there are few examples of these processes in natural settings with relevant caregivers and with long-term maintenance of effects. We implemented a functional assessment and skill-based treatment process with six children with autism in a specialized school setting and extended treatment until challenging behavior was reduced to near-zero levels across multiple staff and settings. Follow-up data indicate that effects were still observed 1 year posttreatment and the use of crisis procedures (e.g., physical restraint) was eliminated for all participants.

Risk factors for challenging behaviour and psychopathology in adults with Down syndrome

BACKGROUND

This study explored the role of demographic, psychosocial, stress and life event-related risk factors for psychopathology and challenging behaviour in a clinical sample of adults with Down syndrome.

METHOD

A convenience sample of adults with Down syndrome seen through a specialised clinic was assessed through interviews and questionnaires specifically designed for use in people with intellectual disabilities.

RESULTS

Recent negative life events and stressors were significantly correlated with mental and behavioural health, and significantly predicted irritability, lethargy and depressed mood. Social avoidance was predicted by stress related to anticipation and social-environmental stressors, and negatively predicted by verbal ability. Ritual-related stress predicted obsessive-compulsive behaviour. Participants who did not have a job or vocational placement were significantly more depressed than participants who did.

CONCLUSIONS

Adults with Down syndrome should be provided increased supports for coping with negative life events and stressors. Interventions should also emphasise community engagement, such as employment, and access to psychosocial supports that teach coping and self-regulation skills when faced with stressors and negative life events.

A qualitative study about quality of life in Brazilian families with children who have severe or profound intellectual disability

BACKGROUND

This study investigated the psychocultural perspectives concerning family quality of life among Brazilian families with children who have severe or profound intellectual disability.

METHODS

Individual in-depth semi-structured interviews conducted with 15 mothers, selected by convenience, were analysed using a categorical thematic analysis technique. The themes were examined to allow for an interpretative approach of the results.

RESULTS

Mothers revealed that their children with disabilities had insufficient access to services and support related to health care, transportation and recreation. Family quality of life was negatively affected by financial restrictions and social interaction difficulties. Caring for a child with disabilities seemed to be centred on the mother and religious coping appeared as a common psychological adjustment strategy.

CONCLUSIONS

Improving emotional and psychological cares, as well as social and practical measures comprising income support and access to appropriate health care, were inferred to be the mothers' priorities to improve their families' quality of life.
